I'm seeing the same phenomenon on one of our LANs (on another LAN, I
don't see it). My setup is with RHEL 7, and it is seen on both physical
and virtual servers. I don't see it on any RHEL 5 or 6 servers.
A strange observation: If I start tcpdump, the package drops stop.
(Setting the NIC in promisc mode does not have any impact; it has to be
tcpdump.)
I suspect that it has to do with this:

If this is the case, it's simply because recent kernels classify packets,
and then there's nothing to worry about.
- But Red Hat Support does not share that view. I have an open case with
Red Hat Support about it; lots of stuff has been tried, but we have yet
to reach a conclusion.
